Wondering how much Vitamin C serum you should choose?
It’s a common question in skincare. Many brands claim that the higher the Vitamin C percentage, the better the results — but that’s not always true. While Vitamin C is a powerful antioxidant that brightens skin and helps reduce dark spots, using it in very high concentrations can sometimes do more harm than good, especially for sensitive skin.
More Isn’t Always Better
At the market, you’ll often hear: “The higher the Vitamin C, the better the results!” But in reality, very high concentrations (20%+) can backfire:
-
Cause redness, stinging, or dryness, especially for sensitive skin
-
Be more prone to oxidation, which makes the serum less effective
-
Lead people to use it less often, which lowers results
When to Use It
Vitamin C is photosensitive, which means sunlight can reduce its stability and benefits.
-
Best time: Evening, so it works with your skin’s natural repair cycle.
-
If used in the morning, always pair with broad-spectrum SPF to prevent sensitivity.
A Balanced Approach
The most important factor isn’t chasing the highest percentage, but finding a gentle, stable formula you can use consistently.
That’s why Viva Health’s Vitamin C Serum uses a subtle, stable amount of Vitamin C, enriched with:
-
Rosehip Oil
-
Argan Oil
-
Sweet Almond Oil
-
Evening Primrose Oil
-
Vitamin E
This nourishing blend helps brighten skin, fade dark spots, and promote a more even, radiant complexion — without the harsh side effects of high percentages.
💡 Takeaway: Choosing a gentle, well-formulated Vitamin C serum and using it correctly is the key to healthy, glowing skin, not chasing high percentages.
